Schwab: You were very clear and right. I also asked in squeak-dev and Andres Raab said:<br><br>&quot;The socket interfaces are entirely asynchronous, i.e., there is no
blocking. Sockets have semaphores associated with them that are
signaled when anything interesting is happening. Check out methods like
Socket&gt;&gt;sendData: to see how this stuff works together.&quot;<br><br>Thanks!<br><br>Mariano<br>

be a way to block the UI until something happens, but that should not be done

[Pharo-project] Question about Socket<br></font><br></div>
<div></div>Hi folks: I am preparing my SqueakDBX talk for ESUG and I am doing 
some comparisons between a database driver with an external library trough FFI 
and a native driver. I know FFI locks the VM until the function it is being 
invoked, finishes. But I don&#39;t know what happens with Sockets. Do sockets lock 
the hole VM until you obtain a response?<br><br>Thanks for any light in this 
field. <br><br>Best,<br><br>Mariano<br></div></div></div>
